Question

4-For the manometer shown in the Fig. below contains oil and water.For the column heights indicated what is the pressur differential between pipes A and B. CDI water water 650) 20 10 Glycerin S.G-1.26 oil o-o.as S.G 0.85 Dimensions in cm S-The inverted U-tube manometer contains oil S.G.-0.9and water. The pressure differential between A and B, pA-PB is-5kPa Determine the differential reading,h Oil 0.2 m 0.3 m Water 9-Air flows through a pipe at a rate of 200L/s.The pipe consists of two sections of diameters 20cm and 10cm with a smooth reducing section that connects them. The pressure difference between the two pipe sections is measured by a water manometer. Neglecting frictional effects, determine the differential height of water between the pipe sections. Take air density to be 1.2kg/m Air 200 L/s 10 cm 20 cm
